To all whom it may concern.-

Be it known that I, ALFONS MAUSER, a citizenof the GermanEmpire,residingat Cologne- Ehrenfeld, in the Province of the Rhine, Germany, have inventedcertain new and useful Improvements in Machines for the Manufacture of Casings, of which the following is a .description, referencebeing had to the accompanying drawings, and to the figures of reference marked thereon;

This invention relates to machines employed in the manufacture of extremelylight and yet resistant vessels or casings, preferably of thin sheet-iron, aluminium, or the like specially adapted for providing cheap, light, and handy cases for transporting carboys and bottles of acid, valuable liquids, and the like.

The object of theinvention is to provide a simple and eifective machine which will shape and corrugate the vessel from a blank at a single operation.

In the accompanying drawings, Figure 1 shows a fiatblank. Fig. 2 shows it formed into acylinder. Fig. 3 shows the cylinder rounded over at one end according to this invention. Figs. el and 5 show a hexagonal tapered vessel in elevation and plan, respectively, formed in accordance with this invention. Figs. 6 and 7 are two similar views of an oval-tapered vessel. Figs. 8 and 9 are similarviews of a rectangular tapered'vessel. Fig.

10 is a sectional elevation of my improved machine for shaping the vessels. Figs. 11 and 12 are plan and elevation, respectively, of a rounded-over vessel.

' The manufacture is effected in the following manner:

The base 13 of the machine is arranged horizontally, and supported above it upon standards 12 is a-conical ring or frustum 11.

3 designates the core or former, having longitudinal tapering groove 1. The core will be of a shape to produce any desired contour of vessel, several dilferent forms being shown in Figs. 3 to 9 and 11 and 12. The core 3 is mounted upon and in threaded engagement vwith a vertical screw-shaft 1-1, jonrnaled in gears .15 and 16 and a hand-wheel17 or other operating means.

6 designates a series of levers pivoted at 10 to the base of the core to swing inwardly into the grooves 4, and the upper ends of these levers are being outward within the conical ring 11 and there provided with an'tifrictionrollers 7, which travel up the interior inclined face of the ring when the core 3 is moved upwardly, this upward movement of the core causing the levers to be simultaneously inward toward the core. I

The operation is as follows: A cylinder, Fig. 2, is first formed from a blank, Fig. 1, and placed. upon the core, as shown infull lines, 10, and the shaft 14 is tlien rotated to raise the core, and with it the series of levers which, as shown in dotted lines, Fig. 10, willforce the material inwardly against the core and give it the strengthening flutes or ribs and shape it according to the shape of thecore employed. The opposite movement of the core will cause the levers to swing outwardly away from the finished casing, which may then be removed by reaching down through-thering 11 and lifting it from the core. Any desired number of the levers 6 may be provided, and they may be simultaneously or singly operated;

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be I declare that what I claim is- 1. A machine of the character described, comprising, a fluted core, a series of levers pivoted at one end to one end of the core, and extending longitudinally along the core to fit lengthwise .into its grooves, and a conical ring with which the free ends of the lovers engage, said ring and the core with its connected series of lovers being relatively movable toward and from each other, whereby the conical ring will automatically force the levers inwardly throughout their length into the core-grooves.

' 2. A machine of the character, described,

comprising, a. frame, a fluted core, an annularly-arrangci series'of levers pivoted at one end at the base of the core to swing inwardly and title ngthwise into the co1'e-groovcs-,1neans for moving the core and its series of lovers performed,

longitudinally and a stationary ring on the frame into which all of the levers extend; the ring and the levers being'relatively inclined tocause the automatic inward movement of the series of levers when the core and levers are moved simultaneous in a longitudinal direction.

Y 3. A machine of. comprising, therein, a, fluted" core mounted on the screwshaft for longitudinal movement thereby, a

the character described,

series of levers pivoted at their inner ends to the base of the core to move longitudinally a frame, a screw-shaft journaled the core-grooves throughout their lengths, a conical ring supported rigidly on the frame and in engagement with the free ends of the levers to force them automatically inwardly into the core-grooves as the core and levers are moved toward the ring.

therewith, and adapted to swing inwardly into I In testimony whereof I affix m ysignature in presence of two witnesses.
